The TableProperty class represents a database table or view.
In case the table is a vector spatial table and it has multiple geometry columns, separate entries for each geometry column must be created.
In case the table is a vector spatial table and the geometry column can contain multiple geometry types and/or CRSs, a clone of the property for the individual geometry type/CRS can be retrieved with at(i)
